LASTING-TOOL.

SPECIFICATION forming part of Letters Patent No. 289,861, dated December 11, 1883s@ Application tiled October-15, 1883. (No model.)

view of my improved lasting-tool. Fig. 2 is a vertical longitudinal sectional view of the same. Fig. 3 is another vertical longitudinal sectional View taken on a plane at right angles to Fig. 2.

Referring to the drawings, A designates the main frame of the device, which is approximately U-shaped, and has a longitudinal slot, B, in one of its side portions or arms, C C, and a screw-threaded perforation, D, 'in its connecting portion E.

F is an auxiliary frame, that is adapted to be moved in frame A by means of a screw-bar,l

G, working-in perforation D, and having its lower end secured in a perforation, H, in the cross-block I of frame F.. At each end of crossblock I is pivoted a pair of parallelarms or plates, J J, that are adapted to be brought together or separated by means of a transverse screw-bolt, K, Working through perforations L in blocks M, that are pivoted between the pairs of arms J J. These pairs of arms are further connected and braced by convergent armsNN, pivoted to the free ends of arms J J, and connected by a pin, 0, that moves in slot B, and is guided thereby.

To the free ends of each pair of arms J J is pivoted an approximately U -shaped clamp, P,

having one of its arms serrated, as at Q, and provided with a pivoted serrated wing or jaw, R, that is operated by a set-screw, S, to clamp the leather between face Q and jaw R.

The operation and. advantages of my invention will be readily understood and appreciated. The-clamps are irst attached at each side of the boot, and set apart by operating y forated blocks pivoted between these pairs of arms, the transverse screw working through said blocks, the pivoted convergent connecting-arms having the pin moving in the slot,

and the clamping-jaws pivoted to the free 'ends of the pairs of arms, as set forth.

2. The combination of the main frame having the guide-slot, an auxiliary frame having pivoted arms, means foroperating this auxiliary frame, pivoted convergent connectingarms having the pin engaging the slot, means for expanding the pivoted arms, and clamping mechanism on the end of the latter, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

LOUI SCHREPEL.
